Calling all USS Yorktown CV-5 fans

[FFG-7]

Mark, am I correct that the only info you are missing for that walkway is in the middle were that dip in the walkway is?

Hi FFg-7,

Yes. All I have is a vertical view in the ships plans. I need to know how deep that dip was. I'm guessing it was around 4 ft. I can tell from photos that the dip was necessary to clear the center longitudinal flight deck support beam that extends all the way to the edge of the ramp.

I came up with my estimate by comparing the dip to the height of several sailors in the only 2 good pictures I could find. One on the cover of Legends of Warfare USS Enterprise [CV-6] by David Doyle and the other on Page 34 of Warship Pictorial No. 9 Yorktown Class Carriers by Classic Warship Publishing. I was just wondering if 4 ft. t is a valid guess.

Thanks for any assistance in this.

might be less then 4ft.
Ships Ladder Riser Height Requirements
OSHA 1910.25(e)(2) requires ship stairs to have open risers with a vertical rise between tread surfaces of 6.5 to 12 inches (17 to 30 cm).

IBC 1011.15.2 requires ships ladders to have a maximum riser height of 9 1/2? (241mm).

OSHA came about 35 years after the class was designed.

I strongly suspect that they used the same principle or layout for that dip as was used for the catwalk stairwells to the open air arch ways. I'll try and see if I have anything useful in the plans that I did print out later tonight. I did print out a few catwalk details (not sure how readable the lettering may be, a lot of it wasn't) but I can't remember the specific areas or details off the top of my head.

[FFG-7]

Tracy, I kind of figured it was from a later time period but thought it might be of some use if correct info not found.

Brocky,

If you know the height of the top guard rail above deck level, try using that: may be slightly more accurate than using the height of a sailor. That trick was used by the great British model-maker N A Ough.

[Brocky]

FFG-7,
Thanks. The info will gives me a good idea of how steep the steps would be.

Tracy White,
Thanks for looking. I'll see what you come up with.

81542,
Thanks for the idea about the railing. Question though were the railings of a standard height? And could the be at different heights on different parts of the ship?
But I do think I can use the width of the flight deck in the one of the pictures since it seems the shot was taken dead on the center line of the ship. I could use that to determine the scale of the picture and use it like a scale plan.

Thanks again for the assist.

David - you might be right and they might have inherited some philosophies from the Navy, but I've also seen some 1960s sailors argue that their experience has relevancy to what the Navy was doing for paint in WWII and I know for a fact there were significant differences. So, I tend to be a little cautious about using figures and regulations from different eras.

I'm pulling the plans out tonight to remind myself to look through them tomorrow but I'm too pooped from about six hours of driving to go through them.

[Brocky]

Tracy,

Thanks for looking. There's no rush. I've found that's the beauty of working on a ship model, if one step is held up you've got a 1000 other ones to choose from.

Thanks again,
Mark B.

I posted some of this on the main page, but I'll add a couple of links here so that they're saved.

NOAA has been diving on Yorktown over the past few days, and streaming some amazing footage on YouTube. It looks like the entire event has been cut into one video HERE on YouTube.

Also, there's a separate video from the USS New Jersey museum, specifically on the hangar deck mural HERE.

The Holy Grail of CV-5

[Tracy White]

Now if we can just get someone to do decals in 1/350 and 1/700!

[FFG-7]

& maybe 1/200 scale.

[Guest aka TOMLABEL]

Soooo.....anyone make 1/350 1940-41 Ford Super Delux Woody?

(Never hurts to ask!)

Fantastic that we finally got a picture of the mural! Long time waiting.

Dear all l need your help
l would like to put on the Carrier some signalisation flags and l found this code
HX 2 l have recieved serious damage below water line
and these are flags,
Could it be ok?

Kind reminder ifany of you can help... with Signal Flags... thanks

[FFG-7]

look at pg 2 of this link https://emed.ie/_docs/Medicocork-Intern ... ignals.pdf to see what 3 flags reads HX 2.

[TF17Greg]

Dear all, after hours of search in Naval flag signaling I found out that this is the correct table of signals.
Numbers are not signalled with pennants but with signal flags..square

Check this stunning color picture of, I suppose is Yorktown CV10, signal flags with these codes.

First group (left)
B10
and the second group (right)
075 TURN
But I have no idea of what they mean

[SeanF]

No... Looks more like that's "Speed 20, 075 Turn"

Or, if it's meant to be read in first-to-be-hoisted order:

"075 Turn, Speed 20"

- Sean F.

[BB62vet]

While I was NOT a signalman, I concur with SeanF's reading of the flags as this seems plausible given the flag chart in the prior reply. These were meant for escorting ships in the carrier's immediate group in order to (probably) maintain radio silence by issuing visual signals for maneuvering.

Hope this helps!

[TF17Greg]

No... Looks more like that's "Speed 20, 075 Turn"

Or, if it's meant to be read in first-to-be-hoisted order:

"075 Turn, Speed 20"

THANK YOU...I was tired yesterday and l mixed numbers and
B and speed flags...
